PATHUM THANI — A sand dune that vanished for half a century now attracts visitors to the middle of the Chao Phraya, the main river of the Central Plains, in this satellite province north of Bangkok.
On the days of very low tides in the dry season, a sand dune about 20 metres wide and 100 metres long emerges in the middle of the Chao Phraya River in tambon Sam Khok of Sam Khok district, typically in the evenings.
